My additional advice, which I'm sure most do anyway is.
You can't beat spending 4 or 5 hours going around the different stores - Just to get the feel and touch of the laptops - Amazing just how much it changes your perspective. I set off 2 or 3 alarms in the process
I originaly choose the Samsung because it was one of the very few to offer a Mat Screen, and seeeing the amount of home use I make of it that would've been a big bonus. When i got it home they had changed all models to Gloss - Bastards - If I wanted to look at myself, I'd buy a fu****g mirror.
